Shell scripts require formatting and linting. This skill explains how to use shfmt for formatting and shellcheck for linting, and how to use them together effectively.

Shell script quality assurance combines formatting with linting. Run shfmt first to format your script, then shellcheck to lint it. This two-step process catches style issues, unquoted variables, and portability problems across Bash, POSIX sh, and related shells.
shfmt handles formatting—standardizing indentation, spacing, and code structure. shellcheck performs linting—detecting bugs, non-portable constructs, and common shell pitfalls. Always format first with shfmt, then lint with shellcheck to avoid false positives.
Both tools read from EditorConfig (.editorconfig) and per-project configuration files. shfmt respects formatting preferences like indentation style and line length, while shellcheck loads its rules from .shellcheckrc. Load your preferences to enforce consistent quality standards across your team.
Yes. Both shfmt and shellcheck support Bash, POSIX sh, and related shell variants. Configure each tool's dialect settings in EditorConfig or per-project config to handle mixed shells and ensure portability across your scripts.
shellcheck documents errors as SC-prefixed codes—for example, SC2086 for unquoted variable expansion. Understanding these codes helps you fix underlying shell issues rather than suppressing warnings. The Skill guides common codes to accelerate troubleshooting.
Unquoted variables, incorrect quoting, non-portable constructs, and style inconsistencies are frequent issues. shfmt standardizes formatting to prevent accidental errors, while shellcheck detects logic bugs and portability problems before runtime.
